Query the Atlas over MCP
Agentic Commerce Atlas runs a remote Model Context Protocol server, so AI agents and coding assistants can query this reference live while building agentic commerce software. It is a thin proxy over the site's own structured data, so it always reflects the current content.
https://mcp.agenticcommerceatlas.comTransport: streamable HTTP. No authentication. Free to use, with attribution.
Tools
list_protocols: all core protocols (ACP, AP2, UCP, MCP, A2A, x402, MPP) with maintainer, layer, license, status, and spec URL.get_site_index: the structured Atlas index of machine-readable endpoints, site pages, articles, resources, and protocols.get_protocol: the full record for one protocol by id (for exampleacp,ap2,mpp).search_atlas: search the reference and return the most relevant pages with snippets.get_page: the full markdown of any page by path, for examplelearn/acp-explained.
Directory metadata
MCP directories and reviewers can fetch server metadata directly from the endpoint root. It returns the server name, description, documentation URL, AI access guide, tags, data sources, tool list, and example JSON-RPC requests.
curl -s https://mcp.agenticcommerceatlas.com Connect it
Claude (custom connectors are on the paid plans): open Settings, then Connectors, then Add custom connector, name it "Agentic Commerce Atlas", and paste the endpoint above. There is no authentication, so it connects immediately.
Cursor (or any client that reads an MCP config): add the server to your config.
{
"mcpServers": {
"agentic-commerce-atlas": {
"url": "https://mcp.agenticcommerceatlas.com"
}
}
} Any client that supports remote, streamable-HTTP MCP servers can connect the same way.
Try it from the terminal
List the tools:
curl -s https://mcp.agenticcommerceatlas.com \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}' Look up a protocol:
curl -s https://mcp.agenticcommerceatlas.com \
-H 'Content-Type: application/json' \
-d '{"jsonrpc":"2.0","id":2,"method":"tools/call",
"params":{"name":"get_protocol","arguments":{"id":"ap2"}}}' Other ways to read the Atlas
If you do not need MCP, the same content is available as plain files for AI ingestion:
- /data/site-index.json: a structured index of the site's pages, articles, resources, protocols, and machine-readable endpoints.
- /llms.txt: an index of every page with descriptions.
- /llms-full.txt: the full reference in one file.
- /protocols/: the human-readable protocol directory.
- /data/protocols.json: the structured protocol dataset.
- /data/resources.json: the structured resource dataset.
- Append
.mdto any article URL for clean markdown.
